Salt Lake City to Palm Springs

What the Data Says About SLC to PSP

The Salt Lake City to Palm Springs corridor (SLC → PSP) covers roughly 541 miles and is served by 3 carriers, based on Bureau of Transportation Statistics reporting. Across 6,002 flights in the dataset, this route posts a 90.5% on-time rate with an average delay of 63.7 minutes when flights run late. Over the most recent 24 months of BTS data, 2,029 flights were recorded on this pairing — 5 cancelled (0.2%) and 5 diverted (0.2%). Those baseline metrics tell you what to expect before you book.

Having 3 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 6,002 total flights analyzed, the 90.5% on-time figure is statistically meaningful rather than a small-sample fluke. The 63.7-minute average delay applies only to flights that actually ran late, so it is not the average wait across all departures — the majority of flights on this route depart on time under the BTS definition of a delay (15+ minutes past schedule).

Looking at recent months, May 2025 posted the best performance on this corridor at 98% on-time, while Jun 2024 came in at 80% on-time — a 18-point gap between best and worst recent month. For travelers evaluating the SLC to PSP route, the combination of a 90.5% on-time rate, 63.7-minute average delay, 0.2% recent cancellation rate, and 3 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
